FOLDING TABLE.

Application filed February To all whom it may concern:

' Be it known that I, MAX SKoLNiK, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Folding rlables, of which the following is a specification.

My invention relates to folding tables. An object of the invention is to provide a rotatable table top having a middle board or. member to the longitudinal edges of which leaves are hinged in combination with means whereby rotation of the table top into different positions will cause the top to be in completely unfolded position with both leaves supported, or will cause one leaf to -be supportedl in unfolded position with the other leaf folded, or will cause both leaves to be in folded position.

The full objects and advantages of my invention will appear in connection with the detailed description thereof and the novel features ofmy inventive idea will be parti cularly pointed out in the claims.

In the accompanying drawings, .which illustrate a practical embodimentof my invention,-

' Fig. 1 is a top plan view of the table top in folded position. Fig. 2 is a top plan view of the table top in partly unfolded position. Fig.'3 is a top plan View of the table top in completely unfolded position. Fig. 4' is an elevational view of the table with the top in 'folded position. Fig. 5is a verticall sectional view of the table with the top in folded'position. Fig. 6 is a vertical sectional viewl of the table taken at right angles to that shown iii Fig. 5. Fig. 7 is a view of the table top on the liuc 7-7 of Fig. 3.

As shown in the drawings, I provide a supporting structure which in the embodi ment illustrated consists of four legs 10, the lower ends of which are secured in base vmembers 12, the arrangement being such tudinally. The legs are connected in pairs for their short spacing by transverse rods 14 and the latter are connected centrally by a longitudinal rod 16. The upper ends of the legs 10 are secured in a board 18 which forms the lower member of the table top. An intermediate member 20 of the table top is secured upon the member 18 by screws 22 as best shown in Fig. 6. A board 24,

which constitutes the upper member of the table tap is rotatably mounted by means ofy a stud 26 secured to the lower surface of this member and extending rotatably down through openings in the members 18 and 20, and having a head 28 engaging the lowe` surface of the member 18. rlhe stud 26 may be secured to the top member 24 in any suite able manner, as by screws 30. Figs. 5 and 6 show the stud 26 partly broken away for convenience of illustration. Leaves 32 and 34 are hinged respectively to the two longitudinal edges of the board 24 by hinges 36. In case these hinges are not inset flush with the lower surfaces of the members 24, 32 yand 34 then the intermediate member 20 is provided with grooves 38 in its upper surface, as shown 1n Fig. 6, in order that' the board 24 carrying the leaves 32 and 34.may be rotated -upon the supporting structure. The intermediate member 20 is provided with a recess 40 to receive an arm 42 whose inner end is rotatably mounted on the stud' 26. As will be understood from Figs. 1 and A2, the arm 42 is capable of rotative movement through substantially ninety degrees.v The wall 41 of the recess 40 constitutes a sto for the arm 42 when it has been rotated this amount from its original position as will be understood from Figs. 1 and 7. The outer end of the arm 42 is provided with a rubber tipv44 adapted to frictionally engage the lower surface of the board 24. If desired the following device may be employed to lock the table top in' unfolded position.

Bearings 46 and 48 secured to the lower surface of the member 18 slidably support a rod 50 normally held inwardly yby a coiled spring 52, the inner end of this rod having a head 54 adapted to snap into a notch 56 cut in the head of the stud 26.

The operation and advantages of my invention will now be readily understood. Assuming that the table top is in the folded position shown in Figs. 1, 4 and 5, the leaves 32 and 34 may be lifted and the table top rotated through ninety degrees into the position shown in Fig. 3. The leaves will now be supported in unfolded position by the intermediate member 20. It will be noted that at the same time the arm 42 onv account of frictional engagement of its tip 44 with kthe under surface of the board 24 will be nient with the inner wall 4l of the recess 40, as will be understood from F ig. l. If now the table top is rotated through another ninety degrees into the position shown in Fig. 2, the leaf 32 will drop while the leaf 34 will be held up by the arm 42. Vhen it is desired to restore the table top to completely folded position, the leaf 32 is lifted and the table top rotated back through one hundred and eighty degrees, which restores the arm 42 into its position in the recess 40 and allows both leaves to drop. In case the locking device is used the head of the rod snaps into the recess 56 when the table top comes into the position shown in Fig. 8, and prevents rotation of the table top until the rod is pulled outwardly.

I claim:

1. A folding table comprising a supporting structure, a middle board rotatably mounted on said supporting structure, leaves hinged to the two longitudinal edges of said board and normally occupying a folded position, means wherebyv rotation of said board thru ninety degrees will cause both of said leaves to be supported in unfolded position, a movable member ca rried by said supporting structure engaging said middle board vfor movement with the latter for the first ninety degree movement thereof, and means for then stopping said movable mem` ber whereby rotation of said middle board thru another ninety degrees will permit one of said leaves to drop while the other leaf is supported by said movable member.

2. A folding table comprising a supporting structure, a middle board rotatably mounted on said supporting structure, leaves hinged to the two longitudinal edges of said board and normally occupying a folded position, means whereby rotation of said board thru ninety degrees will cause both of said leaves to be supported in unfolded position, an arm rotatably carried by said supporting structure engaging said middle board for movement with the latter for the first ninety degree movement thereof, and means for then stopping said arm whereby rotation of said middle board thru another ninety degrees will permit one of said leaves to drop while the other leaf is supported by said arm.

3. A folding table comprising a supporting structure, a middle board, a stud projecting downwardly from said middle board and rotatably mounted in the upper portion of said supporting structure, leaves hinged to the two longitudinal edges of said board and normally occupying a folded position, means whereby rotation of said board thru ninety degrees will cause both of said leaves to be supported in unfolded position, an arm rotatably mounted at one of its ends on said stud and having its other end engaging said middle board for movement with the latter for the first ninety degree movement thereof, and means for then stopping said arm whereby rotation of said middle board thru another ninety degrees will permit one of said leaves to drop while the other leaf is supported by said arm.

4. A folding table comprisingl a supporting structure, having a flat horizontal member constituting the upper portion thereof, a middle board, a stud projecting down` wardly from said middle board and rotatably mounted in said horizontal member, leaves hinged to the two longitudinal edges of said boaid and normally occupying a folded position, means whereby rotation o1 said board thru ninety degrees will cause both of said leaves to be supported in unfolded position, and an arm rotatably mounted at one of its ends on said stud and having its other end engaging said middle board for movement with the latter for the first ninety degree movement thereof, said horizontal member containing a recess in which said arm is positioned and said reccsshaving a wall which stops the movement of said arm whereby rotation of said middle board thru another' ninety degrees Awill permit one of said leaves to drop while the other leaf is supported by said arm.

In testimony whereof I hereunto affix my signature.

MAX SKOLNIK.
